Coal Bottom Ash for Portland Cement Production
The coal bottom ash was ground in a ball mill up to a Blaine fineness of 3,463 m 2 /kg, similar to that of the Portland cement (5–8% residue on 45 μm sieve). Several coal fly and ground coal bottom ashes were mixed in the laboratory using a powder mixer. The different ground coal bottom ash and coal fly ash mixes are shown in Table 2.
Uses & Limitations of Rubber Cement | eHow
Items bonded with rubber cement will gradually just "let go" of each other. The adhesive does not simply evaporate; rather, it dries out and leaves a brittle residue where it was originally spread. This residue is not easy to remove and can damage the item it was intended to bond, especially if that item was something fragile like a photograph.
Portland Cement Clinker - an overview | ScienceDirect Topics
Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO 2 and 2CaO.SiO 2), the remainder consisting of aluminium and iron containing clinker phases and other compounds.The ratio of CaO to SiO 2 shall not be less than 2.0.

After that, mix a part of hydraulic cement with three parts of water using the electric drill. The final mixture must have a dirt-like consistency, must be moist, and must stick together while rolled into a ball without leaving the cement residue sticking to your hand. Then use the trowel for pressing the cement into the cracks to fill those.
Adhesive Removers at Lowes
This adhesive eraser works wonders as a sticker remover tool, label remover, or decal remover. It clears away residue from forgotten tape and other tacky messes. Safe for use on hard surfaces like metal, glass, brick, wood, concrete, automotive and non-acrylic plastic surfaces. To use, simply spray the sticky area and wipe clean with a cloth.
